What is libheif?

The HEIF library quietly became a video decoder, then a scientific image container.

libheif is at 1.22.0. Two releases in this window changed what the library is for: 1.21.0 added full read and write support for HEIF image sequences, which also lets it decode most MP4 video, and 1.22.0 opened a public API for arbitrary image components with signed, float and complex pixel types. The releases between them are build fixes and a maintenance patch.

What is python-sounddevice?

python-sounddevice's whole release history is the ASIO licensing problem

This is a small binding released a couple of times a year with one-line changelogs. The defining sequence is ASIO: 0.5.0 removed ASIO support from the bundled Windows DLLs, and 0.5.1 restored it by shipping both variants and letting users select the ASIO build through an SD_ENABLE_ASIO environment variable. Since then the changes have been an explicit_sample_format option for WASAPI, better errors on non-integer arguments, and ARM64 Windows wheels.

The HEIF library quietly became a video decoder, then a scientific image container.

◆ Current state

libheif is at 1.22.0. Two releases in this window changed what the library is for: 1.21.0 added full read and write support for HEIF image sequences, which also lets it decode most MP4 video, and 1.22.0 opened a public API for arbitrary image components with signed, float and complex pixel types. The releases between them are build fixes and a maintenance patch.

◆ Where it's heading

libheif is expanding along two axes at once — time, via sequences and an x264 encoder plugin, and channel semantics, via multi-spectral and filter-array data that has nothing to do with human vision. The ISO/IEC 23001-17 rewrite that picks the codec path from the input is what makes the second axis practical rather than theoretical.

◆ Prediction

The 1.22.0 notes say generic components are currently limited to the 23001-17 codec with JPEG 2000 to follow, so the next release most likely extends that component model to JPEG 2000 rather than opening a third front.

P0.0

python-sounddevice's whole release history is the ASIO licensing problem

◆ Current state

This is a small binding released a couple of times a year with one-line changelogs. The defining sequence is ASIO: 0.5.0 removed ASIO support from the bundled Windows DLLs, and 0.5.1 restored it by shipping both variants and letting users select the ASIO build through an SD_ENABLE_ASIO environment variable. Since then the changes have been an explicit_sample_format option for WASAPI, better errors on non-integer arguments, and ARM64 Windows wheels.

◆ Where it's heading

The package's direction is set by what it can legally and practically bundle rather than by feature ambition. The API is stable and the work is distribution - which DLLs ship, which platforms get wheels - with occasional pass-through parameters added when a host API exposes something users need.

◆ Prediction

Expect continued wheel-platform additions and occasional host-API settings passed through as PortAudio exposes them. Nothing in these entries suggests API expansion beyond that.
